Guys, this thread was originally about how fast the F18 actually is, not how reliable gps-receivers are. So let's have it, how fast is the F18!?:) Uphill, around 14 knots? Downhill around 25 knots? What do you think?
I figure 14-15 up and 20 or so down in good wind. Probably faster if you have the guts to go all out downwind in high wind stuff. This is what i do in my 6.0 and I can't sail it worth a crap so I figure an f18 sailed average should go that fast! maybe I am wrong, but I haven't sailed in too long. this despite being on an island 1 mile from water in perfect weather.
